Good topic, something I need to get a better handle on myself.
I know it's possible, because for the first half of my adult life, I had no problem with alcohol. An opened bottle of wine would go bad before I drank whole thing.
Then I became an elder.
Pretty quickly, my opened bottles of wine would never go bad - gone in a couple of days. Then it was a bottle a night. Then I bought bigger bottles!
After my breakdown and "stepping down", the pattern persisted. My nerves were shot and it was the only thing that helped at all. All the meds pretty much sucked.
Now I'm in a FAAAR better place: I know TTATT; I'm fading; saw a psychologist for almost 2 years; my wife supports me and is seeing TTATT for herself; I'm going to school. This is all great stuff! But I still know I still drink way more than I ought.
It isn't easy to slow down once you're in the habit, but all of the above suggestions seem reasonable.
